I own a 2021 ROG Strix G15 G513QM formatted yesterday for a clean install of Windows 11.
I have installed the audio drivers (UAD - ASUS ROG Dolby NB - 6.0.9360.1) but the Dolby is not detected, the 3 entries of the drivers loaded under the Software Components category in Device Management of the operating system do not appear.
With one of the very first drivers, with Windows 10 I remember it worked, there were other problems but at least the Dolby worked ...
I can't even do tests with other drivers as the driver download support page is no longer reachable from any Asus site ...
